This invention relates to dishwashing machines and has for its objectthe provision of a device of this character of extreme simplicity andcheapness and containing a minimum ofmovable parts, operable with thesmallest possible amount of liquid and exhibiting a minimum of danger ofclogging or obstruction; the provision of a device of this characterwhich can be more easily kept clean than other devices and whereby thedishes can be washed and rinsed with the smallest number ofmanipulations; while further objects and advantages of the inventionwill become apparent as the description proceeds.

In the drawings accompanying and forming a part of this application Ihave shown for illustrative purposes a preferred embodiment of myinventive idea although it will-be understood that these drawings areintended to be merely illustrative of the general principles of myinvention rather than exhaustive of their practical application.

,Fig. l is a vertical longitudinal sectional view through the center ofa machine containing my improvements, corresponding to the line i-l 25of Fig. 2; Figs. 2, 3, and 4 are cross sectional views corresponding tothe lines 2-2, 3-2, and l4 respectively of Fig. l and looking in thedirection of the arrows; Fig. 5 is a horizontal sectional view on theline 5-5 of Figs. 2 and 3; 3 Fig. 6 is a perspective view of the pumpand valve fitting; Fig. 'i is a vertical sectional view through the soapdispenser and control valve and pump corresponding to the line I-I ofFig. 8; Figs. 8 and 9 are horizontal sectional views corresponding tothe line &8 of Fig. 7 and showing the valve in diflerent positions; Fig.10 is a perspective view of the machine in position for use; and Fig. 11shows the same machine in storage.

The casing of my improved dishwashing machine preferably assumes acylindrical form as shown in Figs. 1, 2, 10, and 11 and is made in twoparts, namely: a body part I provided with radial legs 2-2 by which itmay be supported with its axis substantially horizontal as shown in Fig.10 and a cover-part 3 hinged thereto at I transversely along the sideopposite the legs, the two parts meeting along a plane ind cated at 5which is inclined to the vertical. As a result, when the cover 3 israised the entire interior of the casing is thrown open to readyinspection and manipulation and certain advantages of air circulationare secured as hereinafter described; and besides the body-part of thecasing is rendered liquid-retaining up to the level where the coverengages the same. A suitable handle 6 is provided for manipulating thecoverpart and the margins of the cover-part are caused to fit inside themargins of the body-part as shown at I, in liquid-shedding relation.

5 Located inside this casing parallel to but spaced from the uprightends thereof, are two horizontal supports lli|tl adapted to receive insliding relation the terminal supporting projections ll-li of the dishbasket l2. Each support in here consists of a piece of piping braced atits forward and rearward ends to the curved portion of the body-part I.while the basket may be formed in any suitable or desired manner so longas it rests suitably on these supports and is spaced from the two endsof the casing. The top of the basket projects suiilciently above oracross the plane 5 to enable ready insertion and removal of said basket.

Projecting centrally inwardly from one endwall of the casing is a fixedstud Ii, and secured to the interior of the opposite wall oi the casingis a transmission housing It having a hollow socket l'l coaxial withsaid stud. One form of this transmission housing is shown in Figs. 1, 3.and 5 and comprises a vertical sleeve-portion I! having bearing-bushingslQ-ll in which are journaled the vertical shaft 2, provided between saidbearings with a worm 2i and having at its upper and lower ends thedriving-pulley 22 and centrifugal pump-impeller 23 respectively. Formedat one side of this sleeve is a hollow enlarged chamber 24 in which islocated a wormgear 25 meshing with the worm 2i, and itself journaled ona fixed stud 28 mounted in a boss 21 at the rear of the chamber. Carriedby and rotatable with this wheel 26 is a pinion 28 meshing with a gear29 carried by a horizontal shaft 30 which is journaled in a bearing llparallel to and spaced from the socket l'i. This socket I1 is formed ina horizontal projection 22 located near the sleeve ll, but having nocommunication therewith, the interior of the socket I'I communicatingwith a depending pipe-connection 28 parallel to the sleeve it. In thepresent embodiment the bearing 3| and projection 32 are supported byhaving their extremities seated in hollow bosses 24-35 formed on a.metal plate 36 which is fastened to the casing and itself carries inaddition the electric-motor 21 having a driv ing-pulley 38 connected tothe pulley 22 by a belt 39. The face of the gear 25 is covered by aremovable plate 40. 1

Journaled in the socket I1 is a hollow connecting fitting ll havingliquid-circulation-ports 42 carried by the inner end of the shaft 3|].

in its wall adapted to communicate in all positions with the neck 38.Inside the casing this fltting is formed with an enlarged flange 43,having thereon a wrist-pin 44 connected by a pitman 45 with an eccentricpin 46 on a disk 41 The radius of movement of the pin 44 being greaterthan that of the pin 46, rotation of the shaft 20 produces a slowrotation of the shaft 30 and a corresponding oscillation of the flange43.

The mouth .i the fitting 4| inside the casing is flared as at 50 for thereception of the tapered end of a connection 5| to which is attached ahollow pipe 52, here shown as rectangular in cross section, and mountedfor oscillation between one support l and the end of the casing. Carriedby each end of this pipe 52 is a horizontal spraypipe 53, formed on itsside facing the basket with a number of liquid discharge apertures. Theopposite ends of the pipes 53 are carried by a brace 54 which is pivotedon the stud l5. One of the pipes 53 is located above, and the otherbelow the basket, the bottom of the latter being spaced from the casingwall sufiiciently to enable movement of the pipe beneath the samethroughout the necessary range. A hollow threaded sleeve 56 carried bythe fitting 4|, and provided with a head 51 overlapping the pipe 52enables the connection to be held in this fitting with a predetermineddegree of friction, sumclent to enable the flange 43 to effect themovement of the parts while permitting stoppage of the same in case ofany obstruction. An axial screw 58 extending through the sleeve, anddetachably mounted in the transmission housing enables ready removal ofthe spray-pipes whenever desired.

The lower end of the shaft 20 is Journaled in a vertical bearing 60rigid with the axial boss SI of a pump-casing 82 which surrounds thepumpimpeller 23 heretofore mentioned. At one side of the boss 6| the topof the pump-casing is formed with an upwardly-facing outlet-port G3which is connected by means of a vertical pipe 64 with thepipe-connection 33 heretofore mentioned. The bottom-face of thispump-casing is covered by a plate 65 having therein a port 66 oppositethe center of the impeller 23 and communicating by means of a horizontalpassageway 61 with one port 68 of a valve-casing whose remaining wallsare formed with an opposite port 39 and two intermediate ports and II(see Figs. 7, 8, and 9). Extending from this valvecasing at one side,and communicating with the port It! is a flaring conduit 12 whichterminates in an arcuate flange 13 secured to the bottom of the casingl, in register with an outlet-opening I4 therein (see Figs. 1 and 2).The opposite port 1| communicates with a hollow chamber formed in anenlargement 16, the top of which is formed (see Fig. 6) with an uprighthollow boss 'I'I in which is pivotally mounted the pipe-elbow 18 whichcommunicates by means 0! a telescoping-coupling 19 with a funnel 80.

Port 69 of this valve discharges into chute 3| which slants away fromthe machine so that when the machine is set on the drain-board 82 of theusual kitchen-sink 83, the chute 8| will overhang the sink, while thefunnel 80 underlies or is capable of underlying the hot-water-faucet 84with which such sink is ordinarily provided. The lower end of thevalve-casing heretofore described is preferably made entirely open asshown at 85 (see Figs. 3 and 7) so that in the absence of thevalve-member any liquid in the machine has a clear channel of escapethrough the chute.

Rotatably seated in this valve-casing is a frustoconical valve member 86of turning-plug type, provided with a handle 81, by which it may beturned and having its top formed with a tapering socket 88 in which isremovably mounted the tapered neck 89 of a soap receptacle 90. Thisvalve-member is formed with two horizontal passages BI and 92,respectively, separated by a partition 93 which is deflected so as toestablish communication between the socket B8 and the channel 92; andfurthermore the mouth of this channel 92 ispreferably provided, along asurface which is substantially coincident with the exterior of the valvemember, with a screencloth guard 94 as shown in Figs. 7, 8, and 9.Suitable stops are provided (not shown) whereby the movement of thisvalve is confined to an approximate 90 are indicated in full and dottedlines in Fig. 4, in one of which positions the port ill communicateswith port 69 and port II with port 68; while in the opposite .positionthe port Ill communicates with port 68, and port H with port 69. Thechute BI is swiveled to the valve casing to enable it to be turned inany direction desired.

The operation of the device is as follows:

The machine having been located as illustrated in Fig. 10 and thecover-part 3 raised as shown in dotted lines, a basketful of soileddishes is introduced, the cover closed, and the motor started. Thevalve-handle B1 is then placed in the position shown in Figs. 4 and 8(signified by the word Rinse"), the funnel 8|] being thereby placed incommunication with the inlet 66 of the pump, and the outlet-opening l4communieating directly with the chute 8| through the ports 10 and 89.Hot-water is then introduced into the funnel 8B, which is thrownviolently against the dishes through the jet apertures of the pipes 53,while those pipes are very slowly advanced and retracted past thedishes, thus loosening all excepting such accretions as are hardened anddried in place, melting and washing away the greater part of the fattyand greasy substances, and delivering all the same, together with allcrumbs and scraps, freely into the sink (where a strainer can well beplaced to receive the same) without any such circulation of this liquidinside the machine as would tend to induce clogging or obstruction.

After the dishes have been well rinsed, and heated in this way, thevalve handle 81 is moved to the position shown in dotted lines in Figs.4 and 9, (indicated by the word Wash) thereby establishing communicationbetween ports HI and 68 on the one hand, and ports H and 69 on the otherhand. As a result, the liquid thereby caught in the tank is retained andcontinues to circulate, and the operator should at this time actuate thesoap dispenser to deliver to this liquid a charge of saponiiyingmaterial from the container 90. Any liquid now introduced into thefunnel Bil merely runs to waste. It is possible, by turning the valveslowly, to increase somewhat the amount of liquid trapped inside thecasing and thus available for the washing process; but in general it isfound that, as soon as the dishes have been well rinsed and heated,better washing results are secured by the use of a. rather smallquantity of well heated liquid, well supplied with soap, and preservedfrom dilution by the addition of more liquid, than in case a largeramount of liquid be employed. As a matter of fact, after the grease hasbeen removed by the rinsing, very little soap is required and the amountof liquid necessary to the operation of the machine is within thecapacity of a. good sized teakettle in case piped hot water is notavailable.

In the valve-position shown in Fig. 8 the screen 94 has little or nofunction. In the position shown in Fig. 9 it serves to prevent or atleast impede scraps and crumbs from finding their way from the outlet tothe pump and thence to the spray pipes. If at any time the machineshould become clogged by accumulation of crumbs in the conduit 12 it ismerely necessary to lift the valve and soap-dispenser bodily from thevalve seat (as shown by dotted lines at Fig. 3) whereupon the contentsof the outlet are discharged directly into the sink. The exterior ofthis screen can be flushed off at the faucet, added liquid introduced(the valve being first turned brlefly'to rinsing position) and thewashing function recommenced. As soon as the washing has proceeded for afew minutes (and a very brief time is required if the preliminaryrinsing has been well done) the valve is again turned to rinsingposition, and more hot water introduced into the funnel for rinsingpurposes. It is a good practice always between these two procedures toremove the valve and wash oil the exterior of the screen with the faucetto diminish the amount of crumbs which might otherwise be carried intothe spray pipes, although the turning of the valve will itself scrapeoff the greater part of such accumulations.

At the completion of the rinsing the water is turned off, the motorstopped, and the cover 3 opened. If the number of dishes to be washed issufficiently great a second basketful may be introduced and theoperation repeated, the first basketful being left to dry; in the caseof a small family, for which a washing machine is most important, asingle basket will oftentimes be found sufl'icient for the wholeaccumulation, and the same can be left inside the casing where thedishes will dry readily, owing to the heat of dishes and casing and tothe peculiar slant of the working opening which when the cover is open,enables free ingress and egress of air due to convection currents. Theinterior of the casing will be found sufficiently cleansed by thewashing action so that no wiping is required: and no precaution towardsdrainage is necessary excepting to lift the valve off its seat to enablethe pump and casing to discharge their contents into the chute 8|.

The bottom of the base part i is slanted towards the outlet sufficientlyfor drainage purposes; and the bottom of the lower spray-pipe 53 isformed with a drainage aperture HM sufficient to enable gradualdischarge of liquid therefrom while the machine is idle without suchloss of liquid as shall impair the operation of the machine.

The particular soap-dispenser illustrated in Fig. '7 comprises anupright container having in its lid a slidably mounted vertical rod 96provided at its top with an operating button 91 and at its bottom with astopper 9B which closes from below the outlet-aperture of saidcontainer. Inside this container I have shown a stirrer 99 consisting offingers projecting from a hub which is movable along a sharply slantedspiral ill!) with which said rod is formed. This rod is normallymaintained at its uppermost position by means of a spring illl, butwhenever it is d epressed the stopper 98 is displaced from its seat. andthe stirrer rotated by the effect of the spiral,

thereby breaking up the contents of the container and ejecting a portionof the same into the duct 92. Liquid soap can be used in the samecontainer if the stopper 9! be made of suitable material such as rubber.Indeed the entire container can be omitted and merely the neck 89 left,provided that its upper extremity projects above the liquid level, whichis itself very low since only a little liquid is ever contained insidethe casing. The necessary soap can then be supplied directly to thisneck by means of a spoon from the original package.

It will be observed that no mixing of rinse water and wash-water canpossibly occur, since the opening of the valve necessary to enable theintroduction of rinse water itself discharges the wash-water into thesink, and only rinse-wateris delivered to the pump. This machineexhibits numerous additional practical advantages, among which are thefact that the entire mechanical and rotating elements are carried by asingle transmission housing thereby enabling the necessary machining tobe effected with minimum expense; the fact that no packing orleakage-preventing joints of any kind are employed, the verticalmounting of the impeller shaft in its surrounding sleeve preventingoverflow of liquid without necessitating any packing glands at thispoint (although it is possible to provide overflow apertures I02 ifdesired to guarantee any excessive amount of liquid from so raising thelevel so as to inundate the transmission housing) and no packing glandsare necessary between the socket I1 and fitting 4|, since their joint islocated inside the casing where leakage is unimportant; the fact thatthe pump, valve, and transmission elements are very small andinexpensive to make; the fact that the machine as a whole is very lightand inexpensive; and that when not in use it can readily be stood on endin the closet as shown in Fig. 11, that end of, the body part I which isopposite the mechanism being preferably provided with a carrying handleI03 for the purpose.

It will be understood of course that a great many changes in design,appearance, construction, and relation of parts can be made withoutdeparting from the scope of my invention and while I have described indetail a preferred embodiment of my improvements I do not limit myselfto any of the details illustrated and described excepting as the sameare specifically recited in my several claims which I desire may beconstrued, each independently of limitations contained in other claims.
